German tractor evades mandatory roadworthiness checks for 20 years
In Germany, roadworthiness tests—known as the Hauptuntersuchung (HU)—apply to most vehicles, including agricultural tractors. While cars and lorries face checks every two years, tractors follow a different schedule. A recent case revealed one tractor had gone without inspection for nearly two decades, raising questions about enforcement.
The HU rules for tractors differ from other vehicles. Those used on public roads must pass their first test five years after registration, then every three years after that. Each inspection takes around 30 minutes, provided the car is clean and in proper working order. The test ensures compliance with the Road Traffic Licensing Regulations (StVZO) and the Vehicle Registration Ordinance (FZV).
Agricultural tractors with a top speed of up to 40 km/h, however, must undergo an HU every 24 months—no matter their weight. Despite this requirement, authorities do not automatically remind owners of upcoming deadlines. There is also no system for routine checks on whether tractors have completed their mandatory inspections. Enforcement usually happens by chance. Police or regulators may spot an overdue HU during traffic stops or random checks. The Central Vehicle Register can verify inspection status only when given a vehicle identification number for a specific case. In one instance, a tractor had missed its HU for roughly 20 years before the violation was detected, leading to a formal penalty. The law does not allow licensing authorities to conduct broad reviews of HU compliance. Without proactive monitoring, some vehicles may remain unchecked for years until an officer notices the oversight.
The HU system relies on spot checks rather than systematic tracking. Owners must keep their own records to avoid penalties, as no official reminders are sent. When violations are found, authorities can issue fines—but only if the uninspected vehicle is caught in use on public roads.
